What do these two changes have in common?
saliva breaking down a piece of bread
a penny tarnishing
Select all that apply.
both are caused by heating
both are chemical changes
both conserve mass
both are changes of state
Answers
Answer: both are changes of state and both are changes of state
Explanation:
.
The two changes like the Saliva breaking down a piece of bread and a penny tarnishing involves chemical change. Thus, the correct option for this question is B.
What do you mean by Chemical change?A Chemical change may be defined as a type of change that significantly involves the production of new substances from old ones by combining each other with different properties.
The action of saliva is stimulated by the action of the enzyme salivary amylase which hydrolyzed the starch into maltose, a disaccharide. A penny tarnishing involves the dissolution of copper oxide in a mixture of weak acid and table salt.
Therefore, the given two changes have in common that both are chemical changes. Thus, the correct option for this question is B.

3. Endocrine System
4. Nervous System
5. Urinary/ Excretory System
Explanation:
1. Circulatory System- The heart pumps blood and blood vessels such as arteries and veins, transports the blood to every part of our body providing organs and muscles with nourishment.
2. Respiratory System- This system maintains our breathing. It supplies the body with oxygen for cellular respiration.
3. Endocrine System- The glands of the endocrine system secrete chemicals called hormones that regulate most of the processes in our bodies like growth, reproduction, metabolism, etc...
4. Nervous System- The entire nervous system controls all of the other systems of the body and it also transmits information to the brain, such as pain and external sensations.
5. Urinary/Excretory System- This system is responsible for eliminating waste products of metabolism and other materials from the body that are of no use.

D. The bottleneck effect increases the genetic diversity of a population.
Answers
Answer:
Natural selection, mutation, and genetic drift are random events.
Explanation:
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.

What types of waves are sound and light? Explain how they would be classified based on the direction of their particle movement and whether they can move through a vacuum. Use details to support your answer.
Answers
Answer:
Longitudinal versus Transverse Waves versus Surface Waves
One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil up and down. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards. In this case, the particles of the medium move perpendicular to the direction that the pulse moves. This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion.
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the first coil left and right. Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards. In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
A sound wave traveling through air is a classic example of a longitudinal wave. As a sound wave moves from the lips of a speaker to the ear of a listener, particles of air vibrate back and forth in the same direction and the opposite direction of energy transport. Each individual particle pushes on its neighboring particle so as to push it forward. The collision of particle #1 with its neighbor serves to restore particle #1 to its original position and displace particle #2 in a forward direction. This back and forth motion of particles in the direction of energy transport creates regions within the medium where the particles are pressed together and other regions where the particles are spread apart. Longitudinal waves can always be quickly identified by the presence of such regions. This process continues along the chain of particles until the sound wave reaches the ear of the listener. A detailed discussion of sound is presented in another unit of The Physics Classroom Tutorial.
